1. Hello
2. welcome
3. i'm newest of this forum, my question is:
4. in the ESP32-WROOM-32E (8Mbyte) besides the usual I2C GPIO pins on 21 and 22 what other GPIO pins can be configured as I2C?
5. Thank You

All of them, unless they're input-only (or used to connect to the flash, but you can't access those pins on a WROOM-32E anyway) ESP32 chips can route 'slow' signals like I2C to any GPIO internally.

1. I still need some more clarification, what speed in Khz can be reached with slow I2C on the various pins?
2. is it the same for PWM?
3. ie can all pins be configured as such?
4. and what maximum speed in Khz can be reached?
5. Thanks for the support
